Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Absolute maximum ratings apply individually only, not in
combination. Unless otherwise specified, all other voltages
are referenced to GND.
The ADP2108 can be damaged when the junction temperature
limits are exceeded. Monitoring ambient temperature does not
guarantee that T
J
is within the specified temperature limits.
In applications with high power dissipation and poor thermal
resistance, the maximum ambient temperature may have to
be derated.
In applications with moderate power dissipation and low PCB
thermal resistance, the maximum ambient temperature can
exceed the maximum limit as long as the junction temperature
is within specification limits. The junction temperature (T
J
)
of the device is dependent on the ambient temperature (T
A
),
the power dissipation (P
D
) of the device, and the junction-to-
ambient thermal resistance of the package (θ
JA
). Maximum
junction temperature (T
J
) is calculated from the ambient
temperature (T
A
) and power dissipation (P
D
) using the formula
T
J
= T
A
+ (P
D
× θ
JA
).
